Way too many to list at this point FX, but I'd say most of the background alien characters from the Cantina and Jabba's Palace would be right at the top of my mini figure want list. They've tackled most all of the main characters already, outside of a costume change here and there.

I'd love to see some dedicated figure sets. Forget the ships and playsets, though I'd love more of those as well. Lego should just give us some packs of all new figures (4 in each would suffice), since they don't seem to want to send anything else remotely new our way right now.
